MACHINE FOR COVERING PAPER BOXES.

SPECIFICATION forming part of Letters Patent No. 507,605, dated October31, 1893.

Application filed October 6, 1892. Serial No. 448,036- (No model.)

To all whom it may concern:

Be it known that I, MERRICK F. WILSON, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and usefullmprovement in Machines for Covering PaperBoxes, of which the following isa specification.

This invention is an improvement on the one illustrated in LettersPatent granted to me bearing date of Aprillet, 1891, No. 450,275, andconsists in the combination and arrangement of the devices described andset forth in the claims.

Reference will be had to the accompanying drawings, in which- Figure 1is a front view of the machine. Fig. 2 is a side View thereof.

Let A be the frame of the machine, to the top of which is fastened thefour vertical guide posts B, B, B, B. On the top of these guide posts B,there is fastened a connecting frame O, which supports in bearings ashieve roller D. Working in this shieve roller there is a cable 11).,one end of which is fastened to the sliding carriage F. by the bail G.and to the other end of said cable there is a weight H. The carriage F.is held by the keepers J. to the posts B. and moves freely up and downthe range of its movement, since it is counterbalanced by the weight H.,but will remain in any position it is placed by the operator. Thiscarriage F. is provided with two paste vats I. I. and pivoted thereinare paste rollers K. K. and on one side of which there is pivoted asmall roller L. and a rod M and below the rod there is a scraper tolimit the amount of paste adhering to the paste rollers, which scraperis pivoted atm and is adjusted by the screw m. The carriage F. isprovided with a bracket N., supporting the rolls of paper N, N Anadjustable device for cutting OK the paper is held to the frame A by thepost 0. and can be adjusted to the desired heightby raising or loweringthe post 0. The cutting knife P. and its attachments may be adjustedlaterally by the movement of the rod 0 in its fastening with the post 0.This knife P. is pivoted at P and works against the bar P and isactuated by the foot treadle, P through the adjustable rod P connectedto the pin P of the rock shaft to which the knife is attached. On thesideof the frame A there is a bracket Q, to which is fastened by meansof the lug R, the mechanism for holding the box form. This lug R. isprovided with radial teeth, which mesh into similar teeth on the bracketQ and is clamped together by a rose hand wheel 1. The box form issecured to the plate S. which is fastened to the axis S, held inbearings, S and adjusted laterally by the movement of the collars S andS, The collar S is provided with ratchet teeth and a pawl S arreststherevolution of the box form in one direction. The bearings S aresupported by the post V. which is adjustable by means of the keeper andset screw V which keeper is a part of the block V and is held in ways inthe block V which in turn is held by the lug R. This block V ismovedbaek and forward and hence the box form the same to accommodate itto the different strips of paper W. W by means of the link X. one end ofwhich is pivoted to the block V at X and the other end is pivoted at Xto a lever X pivoted to the block V and provided with a handle X bywhich the operator moves the box form to the position of either strip ofpaper.

The operation of the machine is thus: To the plate S. there is screwed aform for holding the box to be covered. And the paste pans are suppliedwith paste and the rolls of paper required for the covering are placedin the brackets N. and the ends thereof are trained under the roller L.and over the paste rollers K. K and down between the knife P. and itsabutting bar P as shown by W. and W. The paper thus falling in avertical position and having to pass under the roller L. it enwrapsquite asection of the paste rolls K. K which gives time and surface forimparting paste to the paper, and frictional contact with the surface ofthe paste roll suflicient to drive it by the paper being drawn over it.Horizon tal machines for the purpose require an additional roll or a barto train the paper around a sufficient section of the paste roll toaccomplish the same ends. The operator places a box on the form on theplate S. and draws forward the sheet of paper W. which is coated withpaste and by revolving the box on the axis S wraps the paper around itand then cuts it loose from the strip by his foot actuating the knife bythe treadle and should he require an additional strip to be pasted tothe box he shifts the form to the position of the strip WV by the leverX. and applies the strip of paper in like manner. The paper for thecovering after being coated with paste requires time for the paste toact upon it before it is applied to the box lest it may crack or blisterup after it is pasted and should the box which is being covered besmall, requiring considerable time of the operator in applying thecovering, the carriage F may be lowered down quite near the box form,but should the box be large, requiring quite a length of paper at eachoperation, the carriage F. is shoved up the required height to permitsufficient length of paper coated with paste in advance of itsapplication to the box, and thus by simply moving the can riage F. upand down its ways the operator may adjust it to the requirements of theservice, and the machine being vertical takes up less floor space, ismore convenient of operation and by permitting the sheet of paper tofall vertically from the paste roll, avoids the necessity of additionalrollers and rods and thus more readily permits the paper to be trainedover the machine.

What I claim is- 1. A box covering machine having a verticallyadjustable carriage carrying paste pan I. paste roller K. and roll ofpaper N. substantially as described.

2. A box covering machine consisting of a carriage F. carrying a pastecoating device adjustable, vertically and counterbalanced so as to movefreely in its adjustment in combination with mechanism for holding a boxform and a cutting 0E device substantially as shown and described.

3. A box covering machine consisting of a supporting frame A. verticalguide posts B. connecting frame 0. adj nstable carriage F. and weight H.combined and arranged sub stantially as described.

In testimony whereof I hereto affix my signature in the presence of twowitnesses.
